If you want to read something that will chill you to the bone, then read The Ultimate Evil by Maury Terry. In it, he explains that a Satanic cult was ultimately responsible for the Son of Sam killings, and that the "snuff film" industry was real and sold those films to run operations. Both were linked to Satanism. [link to www.amazon.com]

Very well documented sex scandel out of Belgium. There is a bit about a snuff network.

Please be aware that due to the content it is a very difficult article to read, and there are some public photos within the article that are just very sickening. (The author made a concious decision to display them to strengthen the point that these crimes are horrific and real.)

It's a very long read, but it shows how these scumbags can organize such networks.
